l V E N TO R J0me; 01 6/50 ATTORNEY an mus ovnrtso morrre LAKE, wesrrmearoul T6 all whom it may concem Be it known that I, JAMns OvERsoN, a

subject'of the King of Denmark, residing'at Big Lake,-'county of Skagit and State of vide a means for locking stakes inthe ends 'Washington', have invented a new and useful' Collapsible-Stake Log Bunk; and I do hereby declare thatthefollowifn-g is-a full," I clear, andexact specification, such as will enable others skilled in-the art to Which it appertains to make and use the same; r

The; invention is a' device for'h'ol'ding' jlogs' on cars in which the stakes at the ends-may be released fromthe opposite side of thecars.

The object of'the' invention is to; provide logbunks with stakes-in their ends pivoted and locked in-sucha mannerjt'hat'they may" be released from the opposite side of the car and when they are released they will swing about the pivot and drop out of the way;-

- Another" obj ect of the invention is; to proof log bunks so that they-will be held absolutely rigid in the vertical positionand so that they may be released from the opposite side of the car. p

' And a still further object ofthe invention is to provide a nut or' lugs on the end of the bolt used in log bunks for releasing the stakes which will not be 'broken-ofl by logs hitting it. 1

lVith these ends 'inview the invention embodies a long frame divided into two see-- 'tions with small partitions across them, a

vertical memberpivotally mounted in the opposite end of each section, having a hook on'the lowercornerofits inner side a fiat plate with a lug on its end to fit into the hook in each section and bolts witha collar and nut on them threaded into the ends of the'flat plates and extending through the sections so that'they may be turned from the opposite ends of the sections;

. I Other features and advantages of the in vention will appear from the following description taken in connection with the drawings, wherein l Figure 1 is the side elevation of a car 5 showing the bunks holdingthe logs.

arrangement of the-means] for holding and Inthe drawings I have shown my deviceas it will be used wherein numeral '1 indicatesthe long frame which is constructed of three plates-as shown-in Figuree, the center plate being indicated by'the numeral 2 and I the twoside plates'b'y the numerals?) and 4.

Thesection' betweenjthe'j plates 2 and '3 is similar tofth-e section between f the plates 2 and 4 except that they are arranged in opposite dire ctions; therefore I willdescribe the construction: for one section understood 'to apply to either.- I

Astak'e 5 is mounted upon a pin 6 in the which "will be} end ofthe frame as shownin Figure 3 arid may be made asshownwith a hub 7 having a thehub and a vertical T shaped section projecting upward; or it may be made of structura' l" steelv or' wood or in any desired m-anperform the functions? of the section and onone end of thisfsplate holed in it through which the pin 6'passes, 7 'a hook 9 with a recess 10' between it and is a lug 14 as shown in'Figure 3 -whiclrhasaprojection 15 onitto fit into the recess 10 of the stake 5. On the opposite endof the plate llr is"another lug '16 which has' a'.

threadedhole 1'7 in'it intowhichthefrod 18 operates'andin frontof this lug is an' open-F ing'l9 'wh'ichallowsthe rod to'pass through it-has 'a nut" or head 20 on it. This head is constructed in such a manner that it may be gripped by any suitable device for Y turning the rod. Ihave shown it in theshape of half' of'asphere with'twoslots 21-and 22 through it at right angles so that a bar or pipe may be placed, intothe slots to twist the bar. I

have shown a collar 23 screwed on to the end of the rod and locked in the position shown by the set screw 24. Thiscollar is held be? tween two partitions 25 and26 in the section.

' These partitions may be placed in any desiredlocation in the section and the collar 23 may be held to the rod in any desired manner; or it may be made on the rodas shown in Figure .5 and may be placed at the end of the section with the end plate 27 forming one of the partitions. W'hen constructed in this manner all of the partitions and the end plate should be open at the top with slots 28 in them as are made in the intermediate partitions 29 shown in Figure 4:. In Figure 5 I have also shown an alternate construction for the head of the bolt which shows two prongs 30'connected to a base 31 which forms the head of the bolt. It will be seen that a bar or pipe may be placed between these lugs to turn the rod.

In the lower corners of the hook 9 of the stake 5 may benotches 82 to clear the lugs 12 as the stake is in the vertical position shown;

It will be understood that other changes may be made in the construction without departing from the spirit of the invention. One of such changes may be in the manner of the construction of the sections as they may be made of structural steel with the lugs 12 and 13 riveted on, another may be stood from the foregoing description. To

' use'the device it will be placed across the top of a car or two trucks; one being placed a short distance from each end and the stakes 5 placed in the vertical position where they will be locked by turningthe rod 18 from the opposite side of the car. The logs may then be placed across the bunks and the stakes will hold them on the cars. When it is desired to dump the cars the rods may be turned in a counter-clockwise direction which will move the lugs 15 back to the position shown in dash lines in Figure 3 so that the hook 9 will be free to move upward in the are indicated by dash lines 33 and the stake will then rotate about the pin 6 until it drops downward so that it will be entirely out of the way and the logs on the bunk may then roll off of the ends. As these stakes are released from the opposite side of the cars this device eliminates any possibility of the person removing the stakes being hurt by the logs rolling ofi. After the logs have been dumped the stakes may be raised to the position shown and locked by tightening up the bolts.

Having thus fully described the invention,

what I claim as new and desire to secure by Letters Patent is 1. A device of the type described embodying aframe constructed in two similar sections arranged opposite to each other; vertical members in the ends of the sections; said vertical members being so arranged that the one in one section will be at one end of the device and the one in the other at the other end of the device; pins for pivotally supporting these members; hooks on the lower corners of these members; other hooks on horizontal plates which fit into the hooks of the vertical members; lugs in the sides of the sections for holding the horizontal plates freely; lugs with threaded holes in them on the opposite ends of the horizontal plates; openings in the plates adjacent to the lugs; a rod with threads on one end extending lon- .gitudinally through each section; collars on the rods held between partitions in the sections; and suitableheads on the ends of the rods by which the rods may be turned.

2. A collapsible stake log bunk of the class described embodying a frame made in two sections; vertical members in the ends of each section; said vertical members being so other at the other end of the device; pins for pivotally supporting these members; hooks on the lower side of the vertical members; other hooks slidably mounted in the frames to engage the hooks on the vertical members; and a rod suitably mountedv in each section and attached to the hooks in such a mannerthat they may move the hooks backward and forward.

3. A device of the type described comprising a frame made in two sections with small partitions across the sections; vertical members in one end of each section pivotally mounted on pins; said vertical members hearranged that the one in one section will be at one end of the device and the one in the ing so arranged that the one in one section JAMES OVERSON.
